Cons

"We encounter issues sharing IP addresses with other companies using the software."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
